ATTO RN EYE Patented July 16, 1946 I UNITED STATES- PATENT I OFFICE ANCHOR William J. Washam, Harrisonburg, Va.

Application December 12, 1944, Serial No. 567,860 1 1 Theinvention relates to an anchoring device, and more especially to an expansible anchoring member.

The primary object of the invention is the provision of a device of this character, wherein it can be introduced within a bore Within a foundation and automatically locked therein, yet it can be released when the occasion requires, and when locked will firmly and securely hold a guy rod or cable fast in place for supporting purposes.

Another object of the inventionis the provision of a device of this character, wherein the holding power thereof is materially increased, it having spreading wings or blades which assure firm and secure anchorage in earth, and these wings or blades can be locked in holding position or ad just nent, and readily released for the removal of the device, when it is desired to do so.

A further object of the invention is the provision of a device of this character, wherein the securing blades or wings are linked in a manner that they can be uncoupled with ease and dispatch for the easy removal of the device, the latter being of novel construction, and unique in the arrangement of its parts. I

A still further object of the invention is the provision of a device of this character, which is simple in construction, thoroughly reliable and efiicient in operation, strong, durable, readily and easily applied and removed, assuring a firm anchorage, with maximum holding power, and inexpensive to manufacture and install.

With these and other objects in view, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings, which show the preferred embodiment of the invention, and pointed out in the claims hereunto appended.

In the accompanying drawings:

Figure 1 is a side elevation of a device constructed in accordance with the invention showing it being moved to an applied position.

Figure 2 is a fragmentary side view looking toward the outer face of one of its blades or wings.

Figure 3- is a sectional view taken on the line 3-3 of Figure 1 looking in'the direction of the arrows.

Figure 4 is a view similar to Figure 1 showing the device in anchored position.

Figure 5 is a view similar to Figure 4 showing the device adjusted for the unanchoring thereof.

Figure 6 is a sectional view taken on the line 6-6 of Figure 3 looking in the direction of the arrows.

4 Claims. (01. 189-92) Figure 7 is a sectional view taken on the line '1 8--8 of Figure 4 looking in the direction of l the arrows. l

Figure 8 is a detail plan view of one of the links for the blades or wings.

Figure 9 is a view similar to Figure 8 of the other link.

Figure 10 is a detail plan view showing the blades or wings in separated relation for hinge coupling thereof. 1

Similar reference characters indicate corre: sponding parts throughout the several views in the drawings. i 7,

Referring to the drawings in detail, A designates generally a bore within the earth, while B denotes in entirety the earth anchor or holding device constructed in accordance with the invention, which comprises a hold-down shank l0, having an outer eyeterminal II to which is attached a guy wire, cable or the like, not shown. This shank ID has centrally threaded therein an adjusting stern l2, which functions as a bolt and protrudes through the inner end of such shank for play through a clearance l3 therefor created in a separable pintle hinge l4 swingingly coupling together a pair of anchoring blades or wings [5, which are outwardly tapered and have curved tips I6 for biting engagement in the earth on the spreading of the said wings or blades when countersunk in such earth, as best seen in Figure 4.- of the drawings.

The wings or blades l5 have pivoted thereto spreader links ll, which have pivoted thereon separably interfitted coupling nuts I8, one being formed with a bifurcation formed with a threaded hole 20, respectively. The bifurcated nut l8 tops the threaded hole nut, and into the hole 20 of the latter nut is detachably engaged the end 2! of the stem l2, which end 2| has an annular abutment shoulder 22 for contacting the nut having the bifurcation l9, so

that both nuts will be separably coupled together by this end 2|, as best seen in Figure 3 of the drawings.

The shank ID at its inner end is formed with an externally enlarged head 23 which when con tacting the hinge l4 lock the wing or blades l5 in an outwardly spread condition and in anchoring position, as best-seen in Figure 4 of the drawings, this being effected by turning the shank III on the stemlZ in one direction, then by reverse turning of such shank the blades or wings I 5 can be released from locked condition, which is best seen in Figure 1 of the drawings.

The stem I2 is provided with a longitudinally I9, and the otherv able by a plug 2'! threaded therein. Thus, the

shank ID will turn on the stem l2 in one direction through the threaded connection therewith,

but will be'held locked against turning in a reverse direction, andin this manner, the stem l2 can be detachably engaged and released from-the,

nuts I8, as best seen in Figure 5 of the drawings.

W'henthe nuts l8 are uncoupled, as shown in Figure 50f the drawings, the device can be withdrawn from the bore A in the earth for the ing of the anchorage therewith.

The'hinge It cannot be separatedwhen the-'- fstemi I2 is engaged in the clearance l3, and to; effect the separation of the wings 01' blades Hi,

this stem must 'be detached from the shank I05 On the form shown in Figure 10, my hinge is shownwith two spaced interengaging hinge lugs (28) on the butts of thewihgs (l5), one of which lug is off-set inwardly from the side edge of the while the other lug is flush with the side edge of the wing. The oiT-set'lug of e'achrwing carries the hinge .pin (29) -,'while the other lug has the pin receiving opening (30) By this arrangement when the wings are hinged together a space provides a clearance forthe stem (1 2)..

To anchor the device B, the parts thereof are arr-ahged as is clearly disclosed inFigure l of the -drawi ngsgahd when anchored, the device will set as shown in Figure 4, then for removal of s'ueh'device, the parts-thereof willhave been ad- "jus as in Figure 5 of the said drawings. The device B affords a tight safe anchorage, 'a-ndZis easily applied and removed.

uWh'atis claimed isz v I 3 L' A device of the kind described, comprising a shank'mean-s on the upper "end of said shank for engagin'ga guy wire or the like, a stem threaded in saidshank through one end thereof, spreading wings loosely hinged to each other and slidable on the stem, and linkage pivoted to the wing and detachably coupled to the stem. 7 2.

'A-device of the kind described, comprising a shank, means on the upper end of said shank for engaging a guy wire or the like, a stem threaded on said shank at one end thereof, wings formed each with spaced hinge lugs on its butts one of which isoi'f-set inwardly from the side edge of the wing and carries a hinge pin, and the other lug having a pin recei ving opening so that h when the wings'are hinged together a clearance to receive the stem is provided therethrou-gh,
